Eval Injection in Rapid7 Insight Agent

An eval() injection vulnerability in the Rapid7 Insight Agent beaconing logic for Linux versions could theoretically allow an attacker to achieve remote code execution as root via a crafted beacon response. Because the Agent uses mutual TLS (mTLS) to verify commands from the Rapid7 Platform, it is unlikely that the eval() function could be exploited remotely without prior, highly privileged access to the backend platform.

The web interface of the Vertiv Avocent UMG-4000 version 4.2.1.19 is vulnerable to arbitrary remote code execution

The web interface of the Vertiv Avocent UMG-4000 version 4.2.1.19 is vulnerable to command injection because the application incorrectly neutralizes code syntax before executing. Since all commands within the web application are executed as root, this could allow a remote attacker authenticated with an administrator account to execute arbitrary commands as root.

Authenticated eval injection in B. Braun Space Battery pack SP with Wi-Fi

An improper neutralization of directives in dynamically evaluated code vulnerability in the WiFi Battery embedded web server in versions L90/U70 and L92/U92 can be used to gain administrative access to the WiFi communication module. An authenticated user, having access to both the medical device WiFi network (such as a biomedical engineering staff member) and the specific B.Braun Battery Pack SP with WiFi web server credentials, could get administrative (root) access on the infusion pump communication module. This could be used as a vector to start further attacks

Dolibarr ERP/CRM < 23.0.2 Authenticated RCE via dol_eval_standard()

Dolibarr ERP/CRM versions prior to 23.0.2 contain an authenticated remote code execution vulnerability in the dol_eval_standard() function that fails to apply forbidden string checks in whitelist mode and does not detect PHP dynamic callable syntax. Attackers with administrator privileges can inject malicious payloads through computed extrafields or other evaluation paths using PHP dynamic callable syntax to bypass validation and achieve arbitrary command execution via eval().

Horilla vulnerable to authenticated RCE via eval() in project_bulk_archive

Horilla is a free and open source Human Resource Management System (HRMS). An authenticated Remote Code Execution (RCE) vulnerability exists in Horilla 1.3.0 due to the unsafe use of Python’s eval() function on a user-controlled query parameter in the project_bulk_archive view. This allows privileged users (e.g., administrators) to execute arbitrary system commands on the server. While having Django’s DEBUG=True makes exploitation visibly easier by returning command output in the HTTP response, this is not required. The vulnerability can still be exploited in DEBUG=False mode by using blind payloads such as a reverse shell, leading to full remote code execution. This issue has been patched in version 1.3.1.
